I have a small front lawn that has quite a few small weeds appearing. I've
looked at various guides and the closest match appears to be Chickweed. Can
someone have a look at a couple of pictures:

and

and let me know if that's what it is?

Would a regular weed & feed product take car of it? I've just been pulling
them up so far but they appear to be spreading.

Thanks in advance,

Rob
